Bonjour!

Hello my name is Clément. I am French and I live living in Paris. I have just finished the university, College is done with me. I like Still, English is my favourite and I would like to improve my command of in this language.

What you wrote is not wrong at all.  Except for minor mistakes, it is considered perfect.  However, there are too many similar structures, "I XXX this, I YYY that."  Makes your writing like a child's.  So I changed the structure around and make it more varied and interesting.
